Damp Clothing:

It’s amazing how a locker full of clothes would appear to be totally dry but the clothes feel cold and damp. This is probably because they have soaked up all the water that has condensed on the inside of the hull.

To reduce the conducted loss of heat which allows dew point to be reached in our clothing and file lockers, we used the closed cell foam material that we had for insulation.

It was bonded in place with contact adhesive covering as much of the surface area as possible. Steel fittings like the chain plates and stanchion bases had to be covered as tightly as possible reducing the volume of water laden air passing over it.

This would have worked better for us if we had used a thicker insulation material.

I believe that Glass Wool is a good insulation material but it would have to be clad with a durable material like vinyl and panelled off.

There was a vast improvement in our lockers once we fitted large vents to cabinet doors top and bottom.

The main double bed has an air gap between the bunk board and the hull which we filled with Glass Wool.

Meme did wonders with vacuum bagging our linen and summer clothing. Provided that all air is removed and the bag is completely sealed, moisture would form only on the outside of the plastic bag. If there was a tiny hole in the bag, moisture in the air would equalise with the moisture laden air in the boat and as soon as dew point was reached the bag would form a pool of water which would be added to., as the day heated and cooled and the bag would remain as an ever increasing reservoir of water.
The coach roof and deck on our little boat is balsa core GRP which is quite good insulation, but there are sections like in way of the fairing of the foredeck to the window frames, which are thin epoxy glass and these areas had to be insulated with the closed cell foam. Other small areas more difficult to get to shall just have to bloom and grow to the end of the season.
